Method of navigation in three-dimensional image data

An apparatus for navigating in three-dimensional electronic image data records, the image data records including three-dimensional partial image data records, the apparatus comprising:

• means for optically displaying at least two mutually perpendicular two-dimensional projections of an image data record, at least one of the two projections including at least one two-dimensional partial projection of at least one partial image data record;
• means for optically emphasizing the at least one two-dimensional partial projection;
• means for functionalizing the at least one optically emphasized partial projection such that the at least one optically emphasized partial projection is selectable by a user input;
• means for receiving a user input directed toward the selection of the at least one functionalized partial projection;
• and
• means for automatically displacing, as a function of the user input, the at least one perpendicular two-dimensional projection not including the at least one partial projection wherein, it is displaced into the at least one partial projection after displacement.
